Fingerbob is a simple Finger daemon which displays formatted user information from an LDAP directory. It is useful when you're in a dark corner of the server room without a GUI and need to find a phone number. Almost every networked computer has a finger client, so Fingerbob provides a simple but universal network address book. It can also provide text documents and list all people in a specified branch of the LDAP directory.
